Summary
SFPUC deputy assistant GM Michael Hyams told LAFCO that Clean Power SF finalized its largest power‑supply agreement — the Gonzaga Ridge wind redevelopment with 147.5 MW of wind and 50 MW/4‑hour battery storage, expected online June 2026 and estimated to create about 200 construction jobs.
Michael Hyams, deputy assistant general manager at the San Francisco Public Utilities Commission, updated the Local Agency Formation Commission on Nov. 15 about Clean Power SF’s power portfolio and a new procurement.
Hyams said Clean Power SF finalized its largest agreement yet to purchase energy from a redevelopment of an existing Merced County wind site, the Gonzaga Ridge project developed by Scout Energy. The project will provide 147.5 megawatts of wind energy and a 50‑megawatt, 4‑hour battery energy storage system. Hyams said the project is fully permitted, has an interconnection approval and is anticipated to come online in June 2026.
Hyams described the battery as a way to store daytime clean energy for evening use when the grid typically relies more on natural gas. He said the project is expected to generate about 200 prevailing‑wage jobs during development and construction and that turbine blades from the decommissioned project will be recycled and used in a process producing approximately 360,000 pounds of concrete additives.
The presentation included Clean Power SF’s 2023 power content information showing its default green product and Super Green product were 100% renewable. Hyams said the new contract will increase the wind share in future power content labels and help meeting state regulatory requirements.
Commissioners thanked Hyams and Clean Power SF staff; several commissioners acknowledged Chair Ronan and Commissioner Preston for their service and joined Hyams in presenting tokens of appreciation. No formal action was taken on the procurement during the meeting.
